The germ and the goal of this project have been fodder for speculation ever since; the most commonly accepted theory is that it was intended to trigger western intervention or pressure on Egypt that would prevent Nasser from nationalizing the Suez Canal.

Initially blamed on the Defense Minister Pinhas Lavon, unrelated court testimony in 1960 would reveal that he was a fall guy.

But in any guise, the hangings this day in Cairo prompted national mourning in Israel and an immediate political shakeup whose dimensions might as well have sprung from this morning’s paper:

The dovish government of Moshe Sharett fell; hawkish founding Prime Minister David Ben-Gurion was recalled from retirement in a Negev kibbutz; and Israel launched a reprisal raid at Gaza. Little more than two years later, Israel and Egypt would contest control of the Suez on the battlefield.
